If your baby has been diagnosed with or you suspect noisy sleeping: grunting, snoring, and squeaking, here is what the evidence says.
The short answer
Newborns are notoriously noisy sleepers. Grunting, squeaking, snorting, cooing, and even brief pauses in breathing are all normal during newborn sleep. These sounds are caused by small nasal passages, immature breathing patterns, and active (REM) sleep. Most noisy sleeping resolves as baby grows.
Key takeaways
- Newborns are notoriously noisy sleepers. Grunting, squeaking, snorting, cooing, and even brief pauses in breathing are all normal during newborn sleep. These sounds are caused by small nasal passages, immature breathing patterns, and active (REM) sleep. Most noisy sleeping resolves as baby grows.
- Usually normal when: Grunting, squeaking, snorting, and cooing during sleep
- Call your doctor if: Breathing pauses longer than 20 seconds
- Varies by age — see the age-by-age breakdown below
“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”
Thousands of parents search for this exact thing. You are not alone.
What Parents Should Know
According to AAP, Mayo Clinic guidelines, newborns are notoriously noisy sleepers. Grunting, squeaking, snorting, cooing, and even brief pauses in breathing are all normal during newborn sleep. These sounds are caused by small nasal passages, immature breathing patterns, and active (REM) sleep. Most noisy sleeping resolves as baby grows. At 0-1 month, newborns are remarkably noisy sleepers, and this catches many new parents off guard. Common sounds include: grunting (especially common, sometimes called "grunting baby syndrome" where baby grunts while learning to coordinate breathing and bowel movements), squeaking and chirping, snorting and snuffling (tiny nasal passages clog easily with mucus), brief pauses in breathing lasting a few seconds followed by a deeper breath (periodic breathing, which is normal), and sighing. These sounds are most prominent during active (REM) sleep. Newborns spend about 50% of sleep in REM. Using a nasal aspirator and saline drops can help if congestion is contributing to noisy breathing. It is generally considered normal when grunting, squeaking, snorting, and cooing during sleep. However, you should contact your pediatrician promptly if breathing pauses longer than 20 seconds.
Normal vs. Concerning
When to Seek Immediate Care
- Breathing pauses longer than 20 seconds
- Baby turns blue or pale during sleep
- Labored breathing with chest retractions (ribs showing), flaring nostrils, or belly breathing
- Baby gasps or chokes repeatedly during sleep
By Age
What to expect by age
0-1 month
Newborns are remarkably noisy sleepers, and this catches many new parents off guard. Common sounds include: grunting (especially common, sometimes called "grunting baby syndrome" where baby grunts while learning to coordinate breathing and bowel movements), squeaking and chirping, snorting and snuffling (tiny nasal passages clog easily with mucus), brief pauses in breathing lasting a few seconds followed by a deeper breath (periodic breathing, which is normal), and sighing. These sounds are most prominent during active (REM) sleep. Newborns spend about 50% of sleep in REM. Using a nasal aspirator and saline drops can help if congestion is contributing to noisy breathing.
1-3 months
Noisy sleeping continues but may gradually improve as nasal passages grow and breathing patterns mature. Some babies develop laryngomalacia (floppy tissue above the vocal cords), which causes a high-pitched squeaking sound (stridor) that is loudest during inhalation. Laryngomalacia is usually benign and resolves by 12-18 months.
3-6 months
Sleep sounds generally become quieter as baby grows. Snoring may persist if baby has nasal congestion or enlarged adenoids. If loud snoring is consistent, mention it to your pediatrician.
6-12 months
Most of the newborn noisy sleeping has resolved. Persistent snoring, gasping, or pauses in breathing should be evaluated as they may indicate obstructive sleep apnea.
What to Tell Your Pediatrician
- Describe when you first noticed noisy sleeping: grunting, snoring, and squeaking and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if consistent loud snoring during every sleep.
- Mention if high-pitched squeaking with every breath that worsens with feeding or crying (possible laryngomalacia).
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Grunting, squeaking, snorting, and cooing during sleep
- Brief pauses in breathing (under 10 seconds) followed by a catch-up breath
- Sounds are loudest during active/light sleep
- Baby is gaining weight, feeding well, and breathing comfortably when awake
- Consistent loud snoring during every sleep
- High-pitched squeaking with every breath that worsens with feeding or crying (possible laryngomalacia)
- Noisy breathing accompanied by poor weight gain or difficult feeding
- Breathing pauses longer than 20 seconds
- Baby turns blue or pale during sleep
- Labored breathing with chest retractions (ribs showing), flaring nostrils, or belly breathing
- Baby gasps or chokes repeatedly during sleep
What You Can Do at Home
- Keep track of when you notice noisy sleeping: grunting, snoring, and squeaking — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that grunting, squeaking, snorting, and cooing during sleep — this is generally within the range of normal.
- At 0-1 month, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Follow any care instructions from your pediatrician. Keep a written log of symptoms to bring to appointments.
- While monitoring at home, seek immediate care if breathing pauses longer than 20 seconds.

Baby's Eyes Rolling Back During Sleep
It is completely normal for babies' eyes to roll back, flutter, or appear to show the whites of their eyes as they fall asleep or during light sleep. This is a normal part of the transition between sleep stages and active (REM) sleep. It is not a sign of seizures when it occurs only during sleep transitions.
Irregular Newborn Sleep Patterns
Newborn sleep is naturally irregular and unpredictable. Babies are not born with a circadian rhythm and cannot distinguish day from night. Sleep gradually becomes more organized over the first 3-4 months. This is biologically normal and not something you are doing wrong.

My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
Adrenoleukodystrophy (ALD) in Babies
X-linked adrenoleukodystrophy (X-ALD) is a genetic disorder affecting about 1 in 17,000 newborns, caused by mutations in the ABCD1 gene on the X chromosome. It primarily affects boys and impairs the breakdown of very long-chain fatty acids (VLCFAs), which accumulate and damage the myelin sheath in the brain and the adrenal glands. The most severe form, cerebral ALD, typically affects boys between ages 4-10 with rapid neurological decline. Newborn screening now enables early detection, and hematopoietic stem cell transplant or gene therapy performed before significant brain involvement can be life-saving.
